- · 12 house cusps. Placidus, with the sign and degree on each. These need a birth time.
- · Aspects with orbs. Sorted from the tightest outward.
- · Every reading. Each planet in its sign, the main aspects and any aspect pattern. With a birth time, each planet's house and your chart ruler too.

Only want your Sun, Moon and Rising? The Big 3 calculator gives those three, plus Mercury, Venus and Mars, in a shorter result.
How to read your natal chart wheel
- 1. The outer ring is the zodiac. Twelve signs of 30 degrees each run counterclockwise.
- 2. AC, at nine o'clock, is your Ascendant. It is the degree that was rising in the east when you were born. The line from AC across to DC is the horizon.
- 3. The small numbers are the houses. House 1 starts at AC and they count counterclockwise to 12. MC, near the top, starts the 10th.
- 4. The symbols inside the ring are planets and points. ℞ marks a retrograde planet. The table under the wheel names each one in words, with its exact degree.
- 5. The lines in the middle are aspects. Olive lines join planets in a trine or sextile, red lines a square or opposition. Conjunctions get no line; check the aspect list for those.
New to charts? Start with the birth chart guide for beginners. Then read the Sun, Moon and Ascendant first, your chart ruler next and the tightest aspects after that. Three or more planets in one sign form a stellium, and the result flags it, along with a Day chart or Night chart tag for whether the Sun was above or below the horizon. For a worked example, see one chart read from start to finish, and for what each house covers, the 12 houses explained.
Example: a natal chart for the J2000 moment
Astronomers date their star catalogs from one instant, J2000: noon Terrestrial Time on January 1, 2000, which was 11:58:56 UTC. Here is that moment as a birth chart for the Royal Observatory in Greenwich, the same way the calculator above lays out a result.
| Planet | Sign | Degree | House |
|---|---|---|---|
| Sun | Capricorn | 10°22′ | 10th |
| Moon | Scorpio | 13°19′ | 7th |
| Mercury | Capricorn | 1°53′ | 9th |
| Venus | Sagittarius | 1°34′ | 8th |
| Mars | Aquarius | 27°58′ | 12th |
| Jupiter | Aries | 25°15′ | 1st |
| Saturn ℞ | Taurus | 10°24′ | 1st |
| Uranus | Aquarius | 14°49′ | 11th |
| Neptune | Aquarius | 3°12′ | 11th |
| Pluto | Sagittarius | 11°27′ | 8th |
| Ascendant | Aries | 23°41′ | · |
| Midheaven | Capricorn | 9°22′ | · |
Three things stand out. The Sun sits 1° from the Midheaven in the 10th house, because it was a few minutes before local solar noon. Mars, Uranus and Neptune share Aquarius, a stellium. And the Moon in Scorpio opposes Saturn in Taurus, less than 3° from exact.
How much does birth time change a birth chart?
We ran the Swiss Ephemeris, the same ephemeris this calculator uses, minute by minute. The numbers show why an accurate birth time matters.
25.1%
A birth time 30 minutes off changed the Ascendant sign for this share of 2026's minutes in New York. At 15 minutes off: 12.5%.
11.0%
A chart cast for noon showed the wrong Moon sign for this share of minutes in New York, 2020 to 2026. The Moon changed sign on 44% of those days.
87.4%
Share of the 2,333 chart calculations our analytics recorded on this page in September 2026 that included a birth time.
Some charts are far more time-sensitive
A new sign rises about every two hours on average, but the signs don't take equal time. The farther from the equator you were born, the bigger the gap.
| City | Fastest (min each) | Slowest (min each) |
|---|---|---|
| London | Aries, Pisces: 52 | Leo through Scorpio: 170 |
| New York | Aries, Pisces: 71 | Leo, Scorpio: 153 |
| Los Angeles | Aries, Pisces: 80 | Leo, Scorpio: 145 |
| Sydney | Virgo, Libra: 80 | Taurus, Aquarius: 145 |
In London a 15-minute error is more than a quarter of the time Aries spends rising and less than a tenth of Virgo's. South of the equator the fast and slow signs swap. If your time is rounded, say "3 pm", calculate the chart for 2:45 and for 3:15 and compare the Ascendant.
Birth chart without a birth time
Leave the time blank. You still get every planet's sign and degree and the aspects between them, cast for noon. The Ascendant, Midheaven and houses are left out, because a guessed time gives a made-up answer, so the wheel has no house numbers and 0° Aries sits at nine o'clock. If the Moon changed sign on your birthday, the result names both signs and the estimated time of the change. In the US the long-form birth certificate, the "vault" copy from the state, usually has the minute.
Method: our own run on October 1, 2026 with pyswisseph 2.10 (the Swiss Ephemeris), tropical zodiac, at New York 40.71°N 74.01°W, London 51.51°N 0.13°W, Los Angeles 34.05°N 118.24°W and Sydney 33.87°S 151.21°E. Ascendant sign checked at every minute of 2026 (UT); figures count minutes of sky time, not people. Rising times measured over one passage of each sign from January 1, 2026 and rounded to the minute. Moon sign compared with local noon at every minute of 2020 to 2026. The September figure is from this page's analytics; a chart calculated twice counts twice.

Birth chart calculator FAQ
Do I need to give my email to get my birth chart here?
No. There is no email step and no account step. Enter your birth date, your birth place and, if you know it, your birth time, and the full chart shows on this page with every reading open. A free account is only for keeping the chart. It adds today's transits and a personalized daily horoscope for it, and works with Google, Apple or an email address.
Is a natal chart calculator the same as a birth chart calculator?
Yes. Natal means relating to birth, so a natal chart and a birth chart are the same map of the sky for the minute and place you were born. This free birth chart calculator draws a Western (tropical) natal chart. A Vedic birth chart, often called a kundli, uses the sidereal zodiac, which sits about 24 degrees behind the tropical zodiac today, shifting most placements one sign earlier. The calculator does not cast sidereal charts.
Which house system does this calculator use, and can I change it?
It uses Placidus, the usual default in Western chart software, and shows Placidus only. To read the chart in Whole Sign houses, call the sign on your Ascendant the 1st house and count signs counterclockwise: a planet in the next sign is in the 2nd house, whatever its degree. A planet's sign and degree stay the same in every house system; only its house can change.
Why does my birth chart look different on another site?
Check three things in this order. First, the birth details: a time off by an hour, or AM entered as PM, moves the Ascendant and every house. In our own run, one hour put the Ascendant in a different sign for about half of all minutes. Second, the zodiac: Vedic sites usually use the sidereal zodiac, which shifts most placements one sign earlier. Third, the house system: Placidus, Whole Sign, Koch and Equal can put a planet in a different house, though they all share the same Ascendant degree.
How accurate is this birth chart calculator?
The planet positions come from the Swiss Ephemeris and are printed to the arc-minute. The time zone and daylight-saving offset are looked up for your birth place and year, so you enter the local clock time from your certificate. For births before about 1970, or in places with wartime clock changes, the historical record has gaps, so check the offset if the chart looks off. In practice the main source of error is an imprecise birth time: the Ascendant moves about one degree every four minutes on average.
Does the chart include Black Moon Lilith or asteroids such as Juno?
No. The chart shows the Sun, the Moon, the eight planets from Mercury to Pluto, Chiron and the North Node. With a birth time it adds the Ascendant, the Midheaven and the Part of Fortune. Black Moon Lilith (a calculated point of the Moon's orbit, not an asteroid) and the asteroids Ceres, Pallas, Juno and Vesta are not part of this chart.
Can I save or print my birth chart from this page?
Without an account, take a screenshot of the wheel, or press Copy for ChatGPT to copy the whole chart as text: every planet, house cusp and aspect. Print the screenshot or paste the text into any document. To keep the chart itself, make a free account with Google, Apple or an email address. It saves this chart and up to five others.
Can I calculate a chart for someone else?
Yes. Enter their birth date, time and place the same way. There is no daily limit, and every reading is open for their chart too. To compare two people, use the zodiac compatibility calculator.
